标准摘要
[中文适用范围]： 描述了用于确定管状聚合物材料的比较燃烧特性的小规模实验室程序。将火焰施加到由金属丝或心轴支撑的垂直位置的测试样本上。移除测试后 [外文原描述]： Describes a small-scale laboratory procedure for determining the comparative burning characteristics of tubular polymeric materials. A flame is applied to test specimens held in a vertical position, supported by a wire or mandrel. Upon removal of the test flame, the extinguishing times and the burning characteristics are determined. This test method can be used to compare the burning characteristics of tubular polymeric materials. This test method shall not be used to compare the burning characteristics of any wire or cable products or any cable management systems. This test method can be used to compare the relative performance of materials, to aid in material selection, for quality control purposes and for quality assurance.
